4 Claims.

This invention relates towrenches, and more particularly to sets .ofwrenches in which each individual wrench may be employed as needed,

:while remaining part of'the'set.

An object of theinvention is to provide 'anovel and improved formof'wrench set; in which a plurality of individual wrenches are movablysecurediin a novel frame or housing, "whereby any selected wrench may-beemployed without disengagementjfrom the housing or frame;

Another objectio'f the invention is to provide a novel wrench set inwhich there" are a plurality of guide and securing members pivoted onacommon pin or shaft, with individual wrenches engaging each of saidguide and securingmembers so as to be movable in relation thereto, andso arranged that any selected wrench may be used withoutdisengagementfrom its guide and securing member.

A further object of the invention is to provide a novel wrench set ofthe type described, in which the guide and securing membersare-eccentrically mounted on the common pin orshaft, allowing anyselected guide and securing member and its wrench to be turnedsubstantially out of axial alignment withtherest-of theguide andsecuring members, for effective use thereof.

' Still another object of the invention is to provide'a novel and"improved wrench set of the type described, in which theindividualwrenches are of the'hexagon typecommonly knownas Allen wrenches, forengagement in matching hexagonallsockets formed in'the heads of screwsor bolts;

Still a further objectof the invention isto-provide a novel and improvedwrench set of the type described, which is'simple in design, inexpensiveto manufacture, and ,whichis highly effective and convenient for itsintended purpose:

' Other objects and advantages of the invention will become apparentfrom thefollowingcdescription of agpreferredembodiment-thereof asillustrated in the accompanying drawings, and in which V 7 long shanks20 of the individual wrenches.

wrenches, 10, i2,

2 one ofthewrenches with its long shank-extended to an upwardly extendedposition.

Fig. 6 is a right side elevation somewhat-similar to that of Fig. 3, butshow-ing'how the upwardly extended wrench of Fig. 5 hasnow-been turnedthrough an angle of ninety degrees in a clockwise direction, alsocarrying with it, its individual guide and securing member; 7

Fig. 7 is a perspective view indicating how the wrench set may begrasped in thehand, with one of its wrenches extended outwardly for use.

Where wrenches are-to be-used, it is-necessary to have a set of wrenchesin graduated sizes, and

when mingled with other tools in the mechanics tool box, or tool drawer,it frequently happens that thevery size of wrench needed has beenmislaid, become separated from the rest of" the set, or otherwise notavailable, and the resulting inconvenience may cause embarrassing delay.The present invention provides a wrench set in which all the wrenchesare mounted in a common holder, yet each-is available for instant use asneeded, without disengaging it from the set, merely by turning thedesired wrench-out of alignment with the others.

' In order to understand-clearly the nature of "the invention and thebest means for carrying'it out, reference may now be had to thedrawings, in which like numerals denote similar parts throughout'theseveral views.

'As'shown, there are a number of individual l4, l6 and I8, each having along shank 20, and a short shank 22 formingan angle with the long shank,both shanks being thus, integralandformed hexagonal in crossse'ction,which'iscommon to the Allen wrenches. The individual wrenches 10,12; i4,lG andWB -are thus similar to each other, but differ-in their crosssectional size, as seen best in [Fig 4, and are alsosomewhat differentin th-e'length of their "shanks.

Stop lugs 24 project outwardly-from each of the Each of, theindividual'wrenches has its long sh ank 20 penetrating loosely through abore 28 formed through the individual guide and securingmembers or hubs30, there being thus one such hub 30 for each of the individualwrenches. The shanks 2E9v of the wrenches are thus seen tobe freelyturnable in the bores ZBofthe'hubs 30, and at the same time freelyslidable axially therein, so that, as seen in Fig. 5, an individualwrench l4 may be elevated by sliding it through its guide bore 28, untilits stop lug '24 comes into contact with the hub 30, blocking furthermovement in that direction of the wrench shank.

As seen best in Figs. 2 and 4, it is preferable to displace the bores 28in the hubs 30, away from the diametral lines of the hubs, and furtherit is seen that the larger diameter bores 28 come closer to the outeredges of the hubs than the smaller diameter bores 28. With all the hubs3i] brought into axial alignment as in Figs. 2 and 4, it is seen thatthere is a frame pin 32 which penetrates eccentric aligned bores 34 inthe hubs 30. The outer ends of the pin 32 may be peened over to retainall the hubs 30 thereon, while yet permitting them to turn freely on thepin. Or, if desired, diameter of the bores 34 4 from, whereby anyselected wrench may be brought into extended position for performingoperative work therewith, all said wrenches being polygonal incross-sectional contour.

2. A wrench set comprising a plurality of hub members, means securingsaid hub members together in assembled relation to each other, a pluinthe two outermost hubs 30 may be made a little smaller than that of theother hubs 30,

and the pin 32 pressed thereon to retain the intermediate hubstherebetween. method is used, then it is seen that the two outgrmosthubs 30 will not be turnable on the pin Each wrench is thus individuallyswivelled, and movable independently of all the other wrenches, so thatit is easily moved into any position to permit use at any angle. Fig. 6shows how any individual wrench may be turned through a full circle of360 degrees, as indicated by the broken line circle 36 in the directionof the arrows and vice versa.

As shown best in Fig. '7, any wrench, such as wrench l4, may be turnedout of alignment with the others, into extended position, so that itsshort shank 22 is ready for insertion into the socket formed in a nut orbolt for turning the same. From Fig. '7, it is seen that the balance ofthe wrenches, namely l0, l2, l4, l6, and I8, combine to form a fine gripor handle, the long shanks of said wrenches being grasped by the threefingers 48,

'42 and 44, while the upstanding long shank of the wrench 22 extendsbetween the fingers 44 and 46. At the same time, the short shanks 22 ofthe wrenches [6, I2, I6 and 22 lie over and against the thumb 48 of thehand. It is obvious that the assembly is firmly gripped.

It is also seen that any one of the individual wrenches may take theposition of the extended wrench M in Fig. 7, and the others will providea firm grip for the hand. Since the wrenches are secured together, inmovable relation to each other to the extent indicated, it is seen thatthe entire assembly is quite compact, and that it may be inserted into acarrying case, for carrying in the pocket, or disposed in the tool case.in similar manner, in a simple envelope type carrying case having aflap secured in closed position by a snap fastener.

Although I have-described my invention in als and arrangement withoutdeparting from the spirit and scope of the invention as claimed.

I claim:
